' DETACIBTAIBLE COVER FOR rims, Books, are.

To all whom it may concern; 7

Be it known that I, OsoAR LOEWENBAOH, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Detachable Covers for Pads, Books, etc.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention pertains to new and useful improvements in detachable covers for pads, notebooks and the like, and has particular reference to means for securing fillers in suitable covers.

In the present methods of detachably securing filler binders within a pair of covers, the securing means sooner or later becomes badly worn and useless and as this means is largely secured to the covers, the same must be discarded as useless. As such covers are more or less expensive, the cost of replacement is considerable.

Therefore the principal object of the invention is to provide an improved binder for fillers and the like which is so associated with a suitable form of cover as to entirely eliminate the difiiculties heretofore experienced. If the binder forming part of my invention becomes worn and useless, it may be readily replaced at a slight cost.

With this general object in View the invention consists in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

In the accompanying drawing:

Figure -1 represents a perspective view of a detachable notebook cover constructed in accordance with the invention.

Figure 2 is a similar view of a binder used in connection with the cover shown in Fig ure 1, these two parts forming the improved structure. a

Figure 3 is a sectional view through the invention showing the association of a filler therewith.

Referring more particularly to the accompanying drawing, the reference character 1 denotes a top cover member of a notebook cover which has a bottom cover'member 2 connected therewith by means of a flexible Specification or" LettersPatent.

lower cover member 2 adjacent this con-' nection with the'flexible back 3;is provided with a pair of upstanding posts 4. In other Words these. posts extend-transverselyof the cover and from the lower cover member 2 to a point adjacent the upper cover member 1, and their free ends are provided with socket engaging heads 5. Any preferred means may be employed for securing these posts to the lower cover member.

The binder 6, which is shown in detail in Figure 2 includes a pair of substantially rectangular elongated plates which may be termed a lower binder plate 7 and an upper binder plate 8, and a flexible back portion 9 connecting the same. The'lower plate 7 is provided with a pair of spaced eyelets 10, the distance between the same being equal to that between the posts 4 on which they are designed to slide. The other or upper 1 plate 8, on the other hand, has a pair of spaced sockets ll which,-when the binder is in use are alined with the eyelets l0 and consequently are engageable' with the heads 5 of the posts 4.

When in use a filler 12 is disposed between I the plates 7 and 8 of the binder and has openings therein receiving the posts 4. In assembling the filler 12 with parts of the invention, the top cover member 1 is turned back to open the notebook cover and expose the posts 4, whereupon the latter may have the eyelets 10 of the plate 7 slid thereover.

WVith the binder laid openin the same-manner as the cover member 1, the filler 12 may be disposed on the plate 7 and the lower cover member 2, whereupon the upper plate of the binder may be turned forward to engage the sockets 11 with the heads 5 of the posts, and when said sockets frictionally snap over said heads, the. binder is retained in the position shown in Figure 3. I

This holds the filler and the several leaves thereof within the cover and permits the top cover member 1 to be opened or closed together with or independently of said leaves. 7 i I From the foregoing description taken in connection with the accompanying drawin it will be seen that in view of the fact that the only attachingmembers carriedv by the cover are the posts 4, and owing to the manner of-attaching the same and the nature of their construction, they will last practically indefinitely, and the cover will parts of the inven;

member, a binder having corresponding portions to engage the opposite sides of a filler, eyelets in one or said portions and slidable on the posts and attaching sockets on the other of said portions for cooperation with the free ends of said posts.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

OSCAR LOEWENBACH.
